3D printing is a method of making 3-dimensional objects by additive means based on digital models. The process of creating these 3D objects is called "printing." The term "3D printer" refers to the device which creates these objects. 3D printers are usually stand-alone devices that can be fed digital data and output physical objects. They find use in many fields and industries, including art, design, and engineering.
3D printers can be used to make anything from toys to business supplies to rocket engines. You can create a wide variety of items at home with 3D printers that are difficult to obtain in stores. However, the 3D printer market is a competitive one. Also, the price can vary depending on the model, brand, and features. To help you choose a 3D printer with confidence, this article will cover 10 factors to take into account.
1. Look Up 3D Printer Categories
There are many styles of 3D printers available, and each has its advantages and disadvantages. Learn the differences between each before making a decision. There are several options to choose from including: Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), Digital Light Processing (DLP), Stereolithography (SLA), and Binder Jetting. SLA printers are faster than most others and produce the highest quality parts of all 3D printing technologies. DLP printers are faster still and they also produce detailed parts. However, they are not as good as SLA printers at creating small details.
2. Think About Purchasing One or Building One
If you’re going to build your 3D printer, you must have the right tools. These tools will include: a drill press, clamps, and vise grips as well as lots of screws, nuts, and bolts. You’ll also need to know how to use these tools so that when something breaks or falls apart (which is bound to happen), it won't be too hard for you to fix. If buying a premade one is more appealing to you, then go ahead and make a purchase. There are several price options available, so you’re sure to find one that is within your budget.
3. Check the Price
Pricing varies depending on the manufacturer, but it's important to compare prices. To get a good deal on a 3D printer, look for those that contain high-quality features for a reasonable cost. Price is not the only consideration — you want to balance cost against performance, build quality, and features. When looking at potential purchases, cross-reference their specs against competitors' products on websites such as Amazon and eBay. Visiting the stores where these products are sold directly may be even better since you can examine everything for yourself and talk to knowledgeable experts.
4. Analyze the Printing Materials Used
The type of filament determines your printer’s resolution and the quality of the finished product. There are a variety of printing materials out there, including: PLA, ABS, PET, and PETG. Knowing how these materials fare during 3D printing will help you choose which best suits your needs. For example, PLA can easily be printed without support structures, but it doesn't hold up well over time or multiple uses. If you opt for ABS, on the other hand, you’ll get better surface finishes and harder parts, but the printing plate may need more preparation beforehand. Additionally, check whether your preferred materials are easily accessible.
5. Verify the Safety Concerns
Make sure a 3D printer is safe for use before purchasing it. It is important to understand the risks associated with 3D printing as well as how to avoid mishaps. Common safety concerns include the following:
- Ensure that the people who use the printer have the skills necessary to operate it. Correct knowledge and skills will prevent injuries if something goes wrong.
- If you have children around, opt for a more child-friendly style. Some models do not require any harmful chemicals while others demand significant safety protocols and good ventilation. Moreover, always adhere to the instructions in the manufacturer's manual.
6. Verify the Level of Excellence
Check reviews from customers. It is also worth checking if the 3D printer meets industry standards and whether the company has quality checks in place. Additionally, find out how much time it takes the printer to print a model and compare that to other printers’ speeds. This information will help you determine if this model is worth your hard-earned money.
7. Possessing A 3D Model
A 3D model is essentially the blueprint for the object you wish to print. You can either create your own model or use a pre-made one from a library. If you're willing to spend the time learning how to use modeling software and making sure everything looks right, you may want to buy a CAD (computer-aided design) or other 3D design programs. If you choose to purchase a pre-made file, be sure it includes the dimensions.
8. Acquire STL files
The STL file format is the most common file type for 3D printing. It saves your 3D designs in a simple text format that is easy to modify. That text then gets uploaded to the printer and printed one layer at a time. You can find STL files online from retailers like Amazon. If you are looking for something specific, check Thingiverse. Thingiverse is an online repository where users post their models (and make them available to others) so they can share their skills.
9. Acquire Slicing Software
The slicer is a computer program that converts 3D models into layers and generates toolpaths. The toolpaths are instructions for the printer to follow in order to end up with a complete 3D part. The slicer software will generate G-code, which is the language that tells your printer how to move along its X, Y, and Z axes as it prints each layer of your design. Check which slicing software will work best with your preferred printer.
10. Find a Group of Brand Owners by Searching Online
You can also search online for 3D printer owners groups. The members will have gone through many of the same situations as you and may have answers to your questions and concerns. Their advice can make your decision easier.
What is a 3D Printer?
A 3D printer is a machine that creates 3D objects from digital models. These machines can be used to make a variety of things including toys, jewelry, and even medical implants. Some people use them to create new parts for their cars and homes. Users can build intricate designs that would otherwise take hours or days to create with traditional methods of production such as subtractive machining.

What Determines a Good 3D Printer?
To understand what makes a good 3D printer, we first need to understand how they work. There are many different types of 3D printers because additive manufacturing can be done using multiple types of materials and curing methods. Each type has its strengths and weaknesses. The best 3D printer for you depends on the traits your printed parts need to have.
